Interface ILlmController<Class>

Controller of TypeScript class-based LLM function calling.

ILlmController is a controller for registering TypeScript class methods as LLM function calling tools. It contains ILlmApplication with function calling schemas, identifier, and class instance for method execution.

You can create this controller with typia.llm.controller<Class>() function, and register it to MCP server with registerMcpControllers:

import { McpServer } from "@modelcontextprotocol/sdk/server/mcp.js";
import { registerMcpControllers } from "@typia/mcp";
import typia from "typia";

class Calculator {
  add(input: { a: number; b: number }): number {
    return input.a + input.b;
  }
  subtract(input: { a: number; b: number }): number {
    return input.a - input.b;
  }
}

const server = new McpServer({ name: "my-server", version: "1.0.0" });
registerMcpControllers({
  server,
  controllers: [
    typia.llm.controller<Calculator>("calculator", new Calculator()),
  ],
});
